Introduction

In addition to understanding things like vector graphics and stitch patterns, one must learn how to deal with fabric, in particular:

• What backing (solid or solvable fabric on the back side) to use
• How different fabric types behave
• What underlay stitching to use in different situations
• Basic stitch types
• Push
• Pull

Underlay

Underlay will stabilize a section that you would like to stitch. Underlays also can be used to create a 3D effect or otherwise change the look of stitched layer on top. There are several kinds of patterns used, however one could distinguish the following three families of underlay:

• No underlay
• Soft (little)
• Hard (a lot)

In addition both soft and hard underlays then can use different patterns like:

• Some kind of lines that are orthogonal to the final stitches. E.g. for an "o" letter you would use a circle, for a larger filled pattern a rectangle.
• ZigZag
• Some kind of diagonal lattices, .e.g \\\ or XXX

Fabric and fiber types

(should later be moved to a different article ..)

• Canevas
• Cotton
• Curdory
• Denim
• Fleece
• Jackets
• Leather
• Nylon
• Lycra
• Knit wool
• Terry
• Twill
• Wovens

Stitch types

There are main stitch types, but we could distinguish three main types

• Running stitches (to stitch finer lines): -------
• Satin stiches (to stitch wider lines, i.e so-called columns): ||||||||
• Fill stitchs (to fill in larger sections in various ways)
